Have a 2012 X25 with Power tower, with standard ballast, besides that the ballast is not filing completely or emptying completely and that sometimes switching between screens takes a while to load up the new screen everything is working as it should be.
Off course some times the power tower does not respond on the first push of the button, but that is nothing for me to worry about.

the only thing is that as far as my dealer can tell me there will not be a (factory under warranty)update for the power tower with new braces and hydraulics, by that I do not get it because as far as i know from this forum all 2012 power towers are updated by the dealer at mc cost.

Must say that the dealer is still working on it so i hope it will be done as it should.
Or is this because I life in Europe and get no service.......?
